My driver's side front door has an intermittent problem with the power locks. Sometimes it stops working entirely and won't respond to my alarm remote or the unlock/lock buttons inside the car. All of the other doors are working fine though. It does this every now and then and stops working for a couple days and then starts working again for another month or so. Its a pain in the ass because I have to disarm the car and then use the key to unlock my door to get in, and then manually lock or unlock only my door when I'm in the car. If it was any other door I wouldn't mind as much but it gets irritating because its on the driver door and I've gotten too used to the luxuries of having my doors unlock when I shut the car off, or lock when I turn it on, and the ability to use keyless entry. Anyone know if this is a problem with the power lock system, or is my aftermarket alarm causing this? I did notice that if all the doors are unlocked (when the problem is occuring) and I manually lock my door, the other doors also lock like they should (they respond to the locking of the driver door). Anyone have suggestions?
